Calculation of Radiative Parameters for A¹Σ⁺-X¹Σ⁺ Electronic Transition of the KLi Molecule

The purpose of this study was to calculate the radiative parameters (Einstein coefficients of spontaneous radiation, oscillator strengths for absorption, Franok - Condon factors, r-centroid, vibrational-rotational wave numbers in electronic transition A¹Σ⁺-X¹Σ⁺ for the molecule KLi (0 ≤ v' ≤ 20, 0 ≤ v" ≤ 36, j' = 0, 30, 50, 70)) and radiative lifetimes of excited electronic state. The vibrational energies and the wave functions are found as a result of numerical solving of the radial wave equation based on potential energy curves constructed in the present work. We compared the calculated energies with experimental values and for the first time obtained the radiative lifetimes.
